FAQ

Questions Luhn Validator owners ask.

  • 01

    How does the validation work?

    The server uses the Luhn mod-10 algorithm to perform a checksum on the digits, ensuring the number is mathematically consistent with standard credit card formats.

  • 02

    Which card issuers are supported?

    The capability currently identifies Visa, Mastercard, and American Express.

  • 03

    Can I use this to check if a card is active?

    No, this capability only validates the mathematical structure of the number. It cannot check if a card is active, has funds, or is stolen.
